I am curious if others see the same on the CTC4, CTC5 or any color sets of that vintage? (I am referring to the post CT-100, 21CT55 sets).

I will hopefully be able to sweep the video amps in the Philco TV-123 chassis (1955 design) shortly; am surprised to see the 2.5 mc figure and wonder if the TV-123 matches the CTC5. For reference, the CT-100 is eyeball flat to 3 mc where it drops quickly to zero at the chroma carrier point.
